Editing is a vital part of creating a film. It can be defined as the placement of shots in a sequence which creates meaning. This includes traditions between shots, the pace of the film and rhythm. Edward Dmytryk created a list of guide lines in terms of editing. First, never make a cut without a positive reason. Audience must be given enough information and then move to the next shot, this way the viewer understands what is occurring in the narrative and is prepared for the next one. Second, when undecided about the exact frame to cut in order to move to the next shot, cut long rather than short. Cutting a shot too early can be very jarring for audiences, therefore is is always better to add a few extra seconds before moving to the next shot.

An example of these techniques being used is in the film Casino by Scorsese in 1995. The film was edited by Thelma Schoonmaker who has also edited films such as The Departed and Wolf of Wall Street. In the scene where Ginger throws the chips in the air causing chaos in the casino, there are numerous long shots of her making eye contact with Sam. There is no dialogue however these characters share a connection. Furthermore, the juxtaposition between characters suggests this relationship will develop throughout the film. Thus, it follows the advice given by Edward Dmytryk. It cuts when appropriate and in a way that isn’t jarring to audiences, and also uses longer shots as opposed to quick cuts.

Casino is a perfect example of how editing can be so powerful.
